DUMPING GAR.

Application tiled October 25, 1922. Serial No. 596,374.

To all whom it may concern:

Be it known that I, GEORGE L. HANCOCK,

a citizen of the United Statesof America,

residing at Geneva, in the county of Ontario and State of New York, have invented certain new and useful Improvements in Dumping Cars; and Ido hereby declare the following to be a full, clear, and exact description of the same, reference being had to the W accompanying drawings, forming a part of this specification, and to the reference numerals marked thereon.

This invention relates to dumping cars and more particularly to the variety having 1 movable gates and mechanism for automatically effecting the opening and closing of the same during the dumping movement, one object of the invention being to provide a car of this variety capable of dumping at either of opposite sides, which is simple and practical in construction and efiicientin operation, as well as comparatively inexpensive to manufacture. Another object is to supply a car of'this 1" character having the operating 'parts advantageously arranged below the top of the car body so as to be out of the way. for example in the use of a power shovel in filling the car, and at the same time so disposed as to avoid injury of the mechanism itself by inadvertent collisions with a shovel or other objects in use.

A further object is the provision of such a car having its gates and associated parts so arranged as to facilitate the dumping of material while at the same time providing against injury of the parts by the material itself while being discharged. To these and i other ends the invention consists in certain improvements and combinations of parts. all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings:

Fi 1 is an end elevation of a car embodymg the present invention.

Fig. 2 is a side elevation of the same.

Figs. 3 and 4 are end elevations similar to Fig. 1 but showing the car body tilted to opposite sides as in dumping.

. Similar reference numerals throughout the several views indicate the same parts.

The embodiment of the invention at present preferred, and herein disclosed by way of illustration .of the principles involved,

comprises preferably a body supporting or truck portion of any suitable construction including in the present instance longitudinally extending beams 5 supported on and secured in a suitable manner to a plurality of transverse beams 6 resting on spring elements 7 carried by journal boxes 8. At 9 are the usual axles carrying wheel 10.

The car body, indicated generally at 11, preferably has onits bottom, in spaced relation on opposite sides of the longitudinal center line. a plurality of supporting knuckles 12 aligned with each other longitudinally on either side of the car. Each knuckle is supported in a socket in a block 13 carried by the corresponding transverse beam 6, from which construction it is apparent that the car body may be tilted about either longitudinal row of knuckle supports 12 as a center for dumping material from the corresponding sides of the body. Y

The body has the substantially box like construction commonly used in such vehicles. the opposite sides being formed by normally closed gates movable to open position for dumping the material. An important feature of the present invention resides in the use of a simple unitary gate 14. supported adjacent its bottom. preferably by a pivotal form of attachment. to the car body adj acent the bottom of the latter. To this end in the present instance the lower edge of each gate is secured. as by means of hinges 15, to the adjacent side of the car bottom and in such a manner that the gate when lowered to open position forms in effect an even continuation of the bottom of the car body. An advantage of this arrangement is that the gate supporting means is located in such a position that it cannot wellbe damaged by contact with objects in use and the extension formed by thegate serves to discharge the material at a greater distance from the wheels. thereby avoiding obstruction of the latter.

The car body may be tilted in dumping by any suitable means which, however, forms no part of the present invention. The tilting movement is preferably limited by flexible elements such as chains 16 secured at one end to the truck portion and at the other to the lower end of an angle bar 17 fastened to the end walls of the car adjacent either side for stiffening the latter. These bars are connected at their lower ends,

a holding the same closed.

as by means of gusset plates 18, with longitudinally extending stiffeners or angle bars 19 fixed to the bottom of the body.

The mechanism for automatically controlling the gates comprises preferably a pair of guide devices, in the present instance sheaves 20, fixed in any suitable manner on the end of the car adjacent its bottom and in spaced relation on opposite sides of the longitudinal center of the body. These guide devices are preferably located adjacent each other for a purpose to appear later. A flexible element, preferably a steel cable 21, is secured at its respective ends as by means of angular clips 22 to each of the gates at a substantial distance above the pivotal support of the latter, the intermediate portion of the cable being carried as shown by the sheaves 20 which position this portion of the cable substantially adjacent the bottom of the car for a purpose hereafter explained. Additional guide devices are preferably employed in the form of bracket keepers 23 located between each gate and the adjacent sheaf 20 to elevate this portion of the cable. These guide devices are preferably disposed adjacent the gates and level with or above the point of attachment of the cable to the latter for the purpose of maintaining an effective leverage on thegate.

Means are provided on the truck portion of the car for deflecting or extending the portion of the cable between sheaves 20 when the car is moved to material carrying or horizontal position as shown in Fig. 1, for the purpose of retracting the cable terminals and thereby closin the gates and uch means comprise preferably an abutment or post 24 in the present instance in the form of spaced strips of metal plate the lower ends of" which are pivotally supported as at 25 on a plate 26 carried by the beams 5. This post extends upwardly as shown between sheaves 20 and is provided at its upper end with a guide device for sheave 27 over which .the portion of the cable between sheaves 20 is passed. Sheave 27 is located at such an elevation relative to the car body and cable 21 is given such a length in conjunction with its arrangement on the body, as to draw the cable taut and fully close both of the gates when the car is moved to the horizontal position shown in Fig. 1. \Vhen, however. the

car body is tilted to either side, as shown in Figs. 3 and 4, the elevation of the car body relative to the abutment or sheave 27, due to the eccentric, support of the body on the knuckles 12, serves to release cable 21 to a suflicient extent to permit the lower gate to be swung by gravity and the weight of contained materials to the open position by the tension of the cable in addition to which the sheaves 20 adjacent to and on opposite sides of the post also provide for its proper moveis desired to dump the contents, it is merely ment. While the cable guiding devices at the points where the cable is turned through the greatest angle are in the present instance in the form of sheaves 20, it is to be understood of course that the cable may be guided throughout by means of sheaves or by bracket keepers such, for example, as those shown at 23, as conditions and judgment may dictate. The above described gate controlling mechanism is preferably em- 7 ployed at both ends of the car as shown.

The operation has been described above in connection with the description of the construction and it is evident that when the car has been moved to the place at which it B necessary to tilt the car in the proper direction, which movement automatically opens the lower gate and discharges the material at a substantial distance from the car wheels. The gates are strongly supported by their hinges and by the cable at each end which parts are so disposedand arranged that there is no obstruction of the material nor possibility of injury to the apparatus by contact therewith. The disposition of the intermediate portions of the cable adjacent the bottom of the car body by the sheaves 20 permits of the location of the extending abutment wholly below the top of the car body to leave the latter entirely unobstructed and also to protect the gate operating mechanism against impacts in loading the car. The body is supported at points sufliciently spaced to insure the desired stability while at the same time requiring but a comparatively small force for tilt ng it in dumping. The invention thus provides a car which is simple, practical and inexpensive in construction, as well as labor saving and efficientin use, and these advantageous features as well as its durable character render it an economical car in operation.
